Batteries, Starters and Alternators


     The charging system keeps a charge in your battery and provides electrical energy for the radio, lights and other features while the car is running. The modern charging system consists of the alternator, battery, wiring and electronic control unit (ECU).

The starter uses electricity from the battery to help turn the crankshaft to start the engine, hence the name starter!

The alternator creates electrical power to run accessories and recharge the battery. It turns mechanical energy from the car’s crankshaft into electrical energy.

The computer acts as a “traffic cop” to control the alternator’s output. It senses when the battery needs charging or when the demand for electricity changes.

The battery is a reservoir of electrical power. Its biggest job is to crank the engine to start the car. The battery also supplies power to the accessories when the engine isn’t running.


Sometimes if your car or truck won’t start, and the engine doesn’t turn over, you could have a bad battery, one that can’t hold a charge. Sometimes it means you left a light or other accessory on, and it drained the battery. And sometimes the problem is really that the alternator isn’t filling it up with new energy while the car is running. Not sure what the issue is, bring it by for our technicians to diagnose which part of the charging system is failing on you.
